Python的合法语句包括:
1. 赋值语句:
```python
a, b, c = 'aa', 'bb', 'cc'
2. 函数调用:
```python
log.write('spam,name')
3. 打印输出:
```python
print('abc')
4. 条件语句(if, elif, else):
```python
if 'iplaypython' in text:
print(text)
5. 序列迭代(for):
```python
for x in list:
print(x)
6. 循环语句(while):
```python
while a > b:
print('hello')
7. 占位符(pass):
```python
while True:
pass
8. 退出循环(break):
```python
while True:
if exit:
break
9. 跳过当前循环(continue):
```python
while True:
if skip:
continue
10. 导入模块:
```python
import math
11. 定义函数:
```python
def my_function(x):
return x * 2
12. 异常处理:
```python
try:
result = 10 / 0
except ZeroDivisionError:
print("Cannot divide by zero")
13. 类和对象:
```python
class MyClass:
def __init__(self, name):
self.name = name
my_object = MyClass("example")
print(my_object.name)
14. 列表推导式:
```python
squares = [x2 for x in range(10)]
15. 异常捕获(except):
```python
try:
code that might raise an exception
except SomeException as e:
handle exception
16. 定义类(class):
```python
class MyClass:
def __init__(self, name):
self.name = name
17. 定义函数(function):
```python
def my_function(x):
return x * 2
18. 定义模块(module):
```python
my_module.py
def my_function(x):
return x * 2
19. 定义包(package):
```python
my_package/
__init__.py
from . import my_module
20. 定义装饰器(decorator):
```python
def my_decorator(func):
def wrapper(*args, kwargs):
print("Before function call")
result = func(*args, kwargs)
print("After function call")
return result
return wrapper
@my_decorator
def my_function(x):
return x * 2
以上是一些Python中常见的合法语句,它们构成了Python语言的基本语法结构。需要注意的是,这些语句只是Python语言中的一部分,Python还支持更多的语法和功能
